Deeper version of M13

Decided to try 240s exposures in each of RGB this time instead of my usual 180s (chosen to balance detail and LP) and it seems to have worked well, especially since there only 5 subs of each colour. Much deeper into the fainter stars too.

M27 (NGC 6853) Dumbbell Nebula

Done this one quite few times now but this is the first time processing with Astro Pixel Processor. Good for gradients and light pollution but a little slow.

M3 (NGC 5272) RGB just a few exposures

Just a few exposures between gaps in the clouds. L not used because of dust on the filter.

M15

First proper imaging session of the season. New mount (EQ6-R) is guiding well with an RMS error of about 0.6″, Coma corrector is working well too. Stars are sharp right to the edges.
